  1. 1. Broad-Scale Patterns in CDOM and Total Organic Matter Concentrations of Inland Waters – Insights from Remote Sensing and GIS

    Författare :Enass Said Al-Kharusi; BECC: Biodiversity and Ecosystem services in a Changing Climate; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Inlandwater; Remote sensing; Sentinel-2 MSI; CDOM; GIS; climate change;

    Sammanfattning : The rise in CDOM (coloured dissloved organic matter) is likely to be relatively more pronounced in remote northern regions. However, there is a lack of monitoring to confirm this. LÄS MER

  3. 2. Lake Dissolved Organic Matter Quantity and Quality : Variability across Temporal and Spatial Scales

    Författare :Roger André Müller; Gesa Weyhenmeyer; Emily Stanley; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; dissolved organic matter; organic carbon; CDOM; lakes; Biology with specialization in Limnology; Biologi med inriktning mot limnologi;

    Sammanfattning : Surface waters receive large amounts of dissolved organic matter (DOM) via runoff from land. The DOM is rich in organic carbon that serves as an energy source for the aquatic biota. During uptake of this energy, aquatic organisms mineralize organic carbon. LÄS MER

  4. 3. Biomass patterns in boreal-subarctic lake food webs along gradients of light and nutrients

    Författare :Gustaf Thomsson; Sebastian Diehl; Dag Olav Hessen; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; boreal-subartic lake; cDOM; epilithon; benthic-pelagic coupling; carnivores;

    Sammanfattning : There is large natural variation in light and nutrient conditions across lakes. In the boreal-subarctic region most lakes are small, shallow and nutrient poor. In such lakes there is often sufficient light to support primary production at the lake bottom. LÄS MER

  5. 4. Uncertainty measurements and validation of ocean colour data in optically complex waters

    Författare :José M. Beltrán-Abaunza; Susanne Kratzer; Samantha Lavender; Paul Glantz; Sven Blomqvist; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ocean colour validation; MERIS; in situ radiometry; water quality; CDOM; marin- och brackvattensekologi; Marine and Brackish Water Ecology;

    Sammanfattning : The thesis addresses validation activities associated with the use of in situ and satellite-based radiometers to assess water quality parameters, such as chlorophyll-a (Chl-a), total suspended matter (TSM) and coloured dissolved organic matter (CDOM- also known as yellow substances, YEL) in CDOM-dominated waters. In paper I, an inter-comparison of in situ radiometers is presented. LÄS MER

  7. 5. Dissolved organic matter across terrestrial and aquatic systems : sources, chemistry and microbial processing

    Författare :Geert Hensgens; BECC: Biodiversity and Ecosystem services in a Changing Climate; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; dissolved organic matter; carbon; leaching; decay; chemistry; terrestrial; aquatic;

    Sammanfattning : The movement of DOM from terrestrial to aquatic systems is a globally significant flux affecting both carbon sequestration and CO2 emissions. Here, DOM dynamics were investigated in terrestrial and aquatic systems within the context of this carbon flux. LÄS MER
